The Long Āgama Sūtra 7.92

7.92

迦葉復言：「諸有智者，以譬喻得解，我今當更為汝引喻。昔者，此斯波醯村有一梵志，耆舊長宿，年百二十。彼有二妻，一先有子，一始有娠。時，彼梵志未久命終，其大母子語小母言：『所有財寶，盡應與我，汝無分也。』時小母言：『汝為小待，須我分娠，若生男者，應有財分；若生女者，汝自嫁娶，當得財物。』彼子慇懃再三索財，小母答如初；其子又逼不已，時，彼小母即以利刀自決其腹，知為男女。」

Kāśyapa again said, “Those who are wise explain things with parables. Now, I’ll explain this for you with a story. Once, this town of Śvetikā had an elder wanderer who was 120 years old. He had two wives. One already had a child, and the other had just become pregnant.

“Soon after that, the wanderer died. His older wife’s son said to the younger wife, ‘I should inherit all the wealth that he had. You’ll get no share of it.’

The younger wife said, ‘Wait a minute, I need a share for my unborn child. If I give birth to a son, then he would inherit a share of the wealth. If I give birth to a daughter, then you’ll marry her, and I’ll get some of his property.’

“The son demanded the father’s wealth politely three times, and the younger mother answered as before. The son attempted to compel her, but he wasn’t successful. The younger mother then used a sharp knife on her lower abdomen to see if she carried a boy or a girl.”
